Possible benign pituaritay tumor.. nervous..

This Friday I am getting an MRI done to see if I have a benign tumor on my pituaritay gland that would explain my serious hormone imbalances. I was not as nervous about a week ago but lately as it is getting closer, I'm getting more nervous. Not for the possibility of it actually being there (since it is apparently a pretty easy fix most of the time) but rather my chances of getting pregnant any time soon. Any success stories or just perspective from anyone who has gone through something similar?
